The party- which featured in the series 11 premiere of TOWIE- saw the couple reveal the sex of their first child in a very original way.

The couple had a cake made for party guests, and as a special twist they decided to colour the sponge to correlate the sex of their unborn baby.

Billie cut the cake to reveal to their party guests that they’re expecting a baby girl!

The couple announced their pregnancy earlier this year, and they got engaged during a romantic holiday in the Maldives following their baby news.

Billie and Greg are set to welcome their first child in the summer.

23-year-old Billie’s baby bump has already started to become visible , and she shared a photo showcasing her changing figure through her Instagram account.

She captured the picture with: ‘Oh hello #babybump ... It appears you have grown over night … Haha.’

We’re sure fashion boutique owner Billie will be excited about all the girly outfits she can dress her little one in when she arrives.
